Paper Abstract

The extended averaging technique and the data windowing technique used in phase-stepping are investigated using the characteristic polynomials. It is shown that the phase measurement algorithms derived using the extended averaging technique are not in general more efficient and may require more samples than those obtained directly from the rules of the characteristic polynomial theory.
